CUTTER-BAR FOR HARVESTERS.

' SPECIFICATION forming part of Letters Patent No. 497,320, dated May16, 1893.

Application filed March 11, 1892. Serial No. 424,493. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES D. HILLABOLD, a citizen of the UnitedStates, residing at Canton, in the county of McPherson and State ofKansas, have invented certain new and useful Improvements in Cutter-Barfor Harvesters; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings,andtothelettersofreferencemarkedthereon, which form a part of this specification.

My invention relates to harvesters, and it consists in certainimprovements on the cutting apparatus for which a patent was granted tome August 25, 1891, No. 458,231.

My present invention aims to simplify and clieapen the construction, andrender it more durable, and easier to repair.

Figure 1 in the drawings is a perspective sectional view of a cuttingapparatus embodying my improvements. Fig. 2 is a bottom plan view of thesame. Fig. 3 is a sectional end elevation, and Fig. at is abottom planview of a modification.

To the finger bar A are secured the fingers B, by bolts a. Cast integralwith each finger is one or more laterally proj ectinglugs b whichfit'against thefront edge of the fingerbar. A groove is formed throughthese lugs, and across the finger parallel with the finger bar, and whenall the fingers are in place, these grooves all lie in the same straightline, and form a trough or guide 0 for the cutter bar D. The knifesectionsEare made as described in my former patent, bybending the baseportion of a triangular piece of metal to fit snugly around acylindrical or polygonal bar, the outer surfaces of these base portionsbeing of a suitable size to slide smoothly in the trough C, over thefront edge of which the knife sections project. A look not D screwedupon the threaded end of the cutter bar, clamps all the knife sectionsfirmly in place. Above the knife sections is placed a guide bar 0'carried on the ends of the arms F, which are fastened upon the top ofthe finger bar by means of screw bolts f. A spring washer f is insertedbe- 5o tween the finger bar and the arm F, so that the wear and tear ofthe guide bar canbe taken up. The lugs?) on the fingers may abut asshown in Figs. 1, 2 and 3. But inasmuch as they are liable to be wornout by grit working into them, they are preferably cut away at one ormore places as shown in Fig. 4, to allow the dirt to drop out as it ismoved along by the knives. I attach the head block G to the cutter barwithout weakening the latter by putting bolts or rivets through it. Thisis accomplished by forming a head at on the bar D and providing the headblock G with a sleeve 9 fitting the bar. The sleeve may also have alongitudinal flange g to which aknife section E can be riveted. The headblock has a hole 9 or other suitable means for the connection' of thepitman therewith.

Having thus described my invention, what I claim, and desire to secureby Letters Pat- 7o ent,is-

1. The combination with a finger bar, of the fingers each having alaterally projecting lug containing a cylindrical groove forming atrough shaped guide open at the top, a cutter bar provided with separateknife sections, each having a cylindrical base to receive the bar andfit the groove, said sections resting upon one edge of the guide, aguide bar rest ing upon the top of the sections, and arms carryin'g saidguide bar, and attached to the finger bar, substantially as described.

2. The combination with a finger bar of fingers having lugs containing acylindrical trough shaped guide, open at the top, a cutter bar, separateknife sections having cylindrical bars to receive the bar, and fit theguide, upon and by one edgeof which said sections are supported, a guidebar resting upon the top of the-sections, arms carrying said. guide 0bar, and springs between said arms and the finger bar, substantially asdescribed.

In testimony whereof I affix my signature in presence of two witnesses.
